I've jumped in w/ both feet (is there any other way to 'jump in'?)
I'm about 500 miles into the clean phase on our MPV. engine has about 140K on it. a little history: we bought the MPV last year, drove out to cincy OH for it, always wanted one of these 4WD models, got a good deal. up to date, all records, recent timing belt, etc. was going through a bit of oil, maybe a qt/1K. had the typical Japanese V6 tappet noise as well.
1st OC, switched to amsoil. I'm not sure, but leaking seemed to get worse, because consumption sure did. tappet noise went away, though. these 3.0 mazda engines have some leaky O-ring issues. so about 2 months ago, changed out the bad O-ring and cam cover gaskets, did an OC w/ some citgo 10W30 that had a rebate, and added a bottle of auto-rx. so far, no consumption whatsoever; in fact, oil is still clean looking. I think I was leaking more oil than burning it. plan to run it to 3K and change to rinse phase. may take awhile, because this is my wife's car and she doesn't drive very far.
only weird thing so far, the tappet noise is still not apparent, but I have a NEW noise, a bit louder, like a 'clanking', present sometimes at idle once it's warmed up, goes away upon acceleration. never had it before, so can't say what it could be. I'll be paying attention to see if it gets worse or not, almost sounds like something on the outside of the motor, not like anything internal, i.e., a bad bearing. I guess time will tell.
